My son went to a Jewish preschool that was actually IN a synagogue, in a very liberal, college town in a very red state (Indiana). Only about half the kids there were Jewish. This was partly because the school had an excellent reputation (which it deserved; I worked there part-time while my son was enrolled).
But, in addition to having a few students who belonged to nominally Christian families (the twice-a-year church, Christmas-is-Santa types), the school also had most of the kids from atheist families, and non-Christian religious families, which is understandable when they are Baha’i or Hindi, because there probably are not enough families to support a separate preschool, but more surprisingly, we had a number of Muslim families. Just like the atheists and Baha’is, they felt their children got so much Christianity from the world at large, and SOOOOOOO much Christmas, they wanted their children’s school to be a sanctuary from it, even if it was Jewish. That says a lot about how interwoven the relentless season of mirth is in this world.
It’s obvious to me since I don’t participate, and it’s work not to participate, but also because I once spent Christmas in Israel, where I could relax, and let it be just another day. And also where I got a chance to talk to some Israelis who had grown up in Israel, then spent time in the US, and told me their perspective on US Christmas.
